Detailed Description

Singleton responsible for loading and applying custom fonts in the Swing UI.

It loads the Luciole font as the default UIManager font (with vertical adjustment) and registers the Material Icons font for use in specialized UI components. This class is accessed via the INSTANCE enum constant.

Member Function Documentation

getCharWidth()

int fr.softsf.canscan.util.FontManager.getCharWidth

(

)

Returns the reference character width based on 'W'.

Uses an internal JLabel context to calculate exact metrics.

Returns

The width of 'W' in pixels.

Here is the call graph for this function:

getCurrentFontMetrics()

FontMetrics fr.softsf.canscan.util.FontManager.getCurrentFontMetrics ( )

private

Retrieves FontMetrics safely.

Guarantees non-null return, resolving the Font and relying on client catch blocks for fault tolerance in headless environments.

Returns

The real FontMetrics object.

getLineHeight()

int fr.softsf.canscan.util.FontManager.getLineHeight

(

)

Returns the total line height (ascent + descent + leading).

Returns

The line height in pixels.

Here is the call graph for this function:

initialize()

void fr.softsf.canscan.util.FontManager.initialize

(

)

Initializes and sets the Luciole font as the default Swing UI font (including scaling/shifting).

It also loads and registers the Material Icons font for UI components.

The UI is updated asynchronously on the EDT using SwingUtilities#invokeLater(Runnable) after fonts are loaded.

Here is the call graph for this function:

loadLucioleFontAsDefaultFont()

void fr.softsf.canscan.util.FontManager.loadLucioleFontAsDefaultFont ( )

private

loadMaterialIconsFont()

void fr.softsf.canscan.util.FontManager.loadMaterialIconsFont ( )

private

Loads Material Icons (TTF) and registers it in the JVM's Graphics Environment.

The font is then accessible using the family name "Material Icons".
